This application claims priority to Singaporean Application Serial No. 10201908029T, filed Aug. 30, 2019, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to payment transactions and, more particularly to, methods and systems for facilitating online payment transactions when the online traffic is more than the usual online traffic or in cases when there is a discounted sale period going on with merchants.

BACKGROUND

In the present time of digital technology, online purchasing for goods/services have gained popularity among many customers. Customers purchase from an e-commerce site or online retailers (hereinafter referred to as ‘merchant site’) using computers or electronic devices sitting at their homes. The merchant site may accept digital payments for payment transactions of the goods/services purchased online by the customers. On many occasions, a typical merchant site may provide advertisements of the goods/services for sale. For instance, during sale seasons or festival seasons, many offers or discounts may be provided to attract old or new customers. In such scenarios, a greater number of customers are expected to visit or make purchases on the merchant site. Consequently, the higher number of customers presence on the merchant site causes increase in the online traffic associated with the merchant site and other components of the payment network.

The increase in online traffic may affect the overall time of payment transactions for customers. More specifically, the high customer traffic may overload the merchant site and other constituents of the payment network and slow down the entire payment transaction process. Consequently, the payment transactions may be delayed, timed-out, dropped-out or even failed due to the high traffic. This may affect the experiences of the customers. When a payment transaction for an online purchase order of a customer drops out, the online purchase order may not be further processed for the shipment. In such a scenario, the customer is not able to take benefit of the discounts offered during the sale period. Moreover, the customer may face issues, such as payment amount deducted but the online purchase order not being confirmed, purchase order out of stock due to incomplete payment, and/or the like. In such cases, the customer may not visit the merchant site in the future due to a negative experience. This may affect business and reputation of the merchant site.

Based on the foregoing, there exists a need to overcome the above-mentioned problems and facilitate a technique where the customers can utilize the benefits of discount offered in the sale period despite high online traffic. More specifically, there is need to improve customer experiences for online purchasing in the high online traffic.

Overview

Various example embodiments of the present disclosure provide methods and systems for providing payment transactions associated with online purchase orders when there is increased online traffic based on reasons including but not limited to periods such as discounted sale period when payment related resources associated with merchant and the payment network are in use more than their usual usage. Techniques disclosed by various embodiments enable locking of the online purchase orders for users at a set price, and actuating the payment transactions against the locked online purchase orders at a later point of time when the online traffic eases or reduced to a reasonable level. The online purchase orders may be locked using a one-time password (OTP) generated by a server such as including but not limited to a payment server associated with a payment network.

In an example scenario, a customer may purchase goods/services from an online merchant using an electronic device associated with the customer. The online merchant, also referred to hereinafter as a merchant site, may include e-commerce websites, online retail stores, e-business service providers, etc. The customer may purchase one or more items from the merchant site. The purchased items are collected in an e-cart. When the customer checks out the e-cart, the merchant site submits the online purchase order information to a merchant server. The merchant server sends a request for generating an OTP to a payment server, upon receipt of the online purchase order from the merchant site. The payment server generates the OTP after receiving the request.

The payment server provides the OTP to the merchant site via the merchant server. The merchant server encrypts the OTP provided by the payment server to generate a merchant OTP. The merchant OTP is stored for usage in completing the payment transaction at a later point of time. Further, the payment server provides the OTP to the customer. In one example embodiment, the payment server may provide the OTP using a registered contact number of the customer. For instance, each of the customer and the merchant may be registered for a program offered by the payment server, under which a discounted price for items can be locked for the customers when there is increased online traffic in periods such as including but not limited to a discounted sale period. With the registration of the customer with the program, registered contact number of the customer is readily available with the payment server. The payment server may also receive the registered contact number from the merchant server. In another example embodiment, the OTP generated by the payment server may be provided to the customer via the merchant server. More specifically, the merchant server can access a customer profile of the customer that is registered to the merchant site and accesses the registered contact number.

The OTP may be sent to the customer through a short message service (SMS) or an Unstructured Supplementary Service Data (USSD) using the registered contact number. Further, the OTP in the SMS or the USSD may be provided in the merchant site by the customer for locking the online purchase order. The merchant site receives the OTP and transfers the OTP provided by the customer to the merchant server. The merchant server encrypts the OTP provided by the customer to generate a customer OTP. The merchant server may provide the customer OTP to the payment server for facilitating the payment transaction of the locked online purchase order.

After generating customer OTP, the merchant server sends a payment transaction request along with the merchant OTP to the payment server via an acquirer server. The payment server further transfers the payment transaction request and the merchant OTP to an issuer of the customer. Further, the merchant server provides the customer OTP to the issuer server. In one case, the merchant server may directly provide the customer OTP to the issuer server, when the issuer server and the acquirer server belong to the same bank institution. In another case, the merchant server may provide the customer OTP to the issuer server via the payment server, when the issuer server and the acquirer server are different.

The issuer server validates the merchant OTP and customer OTP and proceeds further for payment authorization of the locked online purchase order. A payment amount for the locked online purchase order may be debited from the account of the customer after a successful payment authorization. In case the payment authorization fails, then a notification may be sent to the merchant server. The merchant server may further send a notification to the customer to provide one or more alternative payment options for completing the payment transaction.

The methods and systems for providing payment transactions of online purchase orders in online traffic based on the provision of locking the online purchase orders and completing the payment transactions for the locked online purchase orders using OTP generated by a payment server, are further explained in detail with reference to FIGS. 1 to 12.

FIG. 1 illustrates an example representation of an environment 100 related to at least some example embodiments of the present disclosure. The environment 100 is depicted to include a customer 102 associated with an electronic device 104. The electronic device 104 may be a smartphone, a tablet, a laptop, a computer system or any computing device capable of accessing a merchant site. The merchant site includes, but not limited to e-commerce websites, online retail stores, and e-business service providers. The merchant site may be accessed through a merchant interface 106 in the electronic device 104. For example, the merchant interface 106 may be accessed through a mobile-based application, a web-based application or web browser in the electronic device 104.

More specifically, the merchant site may be hosted by a server, such as a merchant server 110. The merchant server 110 may be configured to store an application program and provision instances of the application, such as the merchant interface 106 to customers, such as the customer 102, for facilitating online purchasing of goods/services from the merchant site. In one case, the instances of the application, such as a mobile application of the merchant interface 106 may be downloaded and installed in the electronic device 104. In another case, a web-based application of the merchant interface 106 may be accessed by the customer 102 using the electronic device 104.

The customer 102 may access the merchant interface 106 in the electronic device 104 using a network, such as network 108. The network 108 may include wired networks, wireless networks and combinations thereof. Some non-limiting examples of the wired networks may include Ethernet, local area networks (LANs), fiber-optic networks, and the like. Some non-limiting examples of the wireless networks may include cellular networks like GSM/3G/4G/5G/LTE/CDMA networks, wireless LANs, Bluetooth, Wi-Fi or Zigbee networks, and the like. An example of the combination of wired and wireless networks may include the Internet.

In one example embodiment, the database 118 may be associated with the merchant server 110 storing details of customers, such as the customer 102. In another example embodiment, the database 118 may be embodied in the merchant server 110. The database 118 may be configured to maintain a customer profile for each customer (e.g., the customer 102). The customer profile may include details, such as customer name, shipping address, contact number, email id, etc. Further, the merchant server 110 may be associated with a merchant (not shown in FIG. 1) or may belong to a third-party for hosting the merchant site. The merchant server 110 may be configured to facilitate advertising of goods and/or services offered by the merchant for sale. During the sale, many customers may be attracted to offers and/or discounts provided by the merchant. Moreover, online traffic may be increased due to increase in customer traffic on the merchant site. In such online traffic, the customers 102 may be engaged in online purchasing in the merchant interface 106.

In an illustrative example scenario, when the customer 102 checks out, an online purchase order that includes one or more goods/services may be collected in an e-cart. The e-cart is displayed to the customer 102 in the merchant interface 106 during the checkout, which is shown in FIG. 5A. In such scenario, when the customer 102 checks out, the online purchase order is submitted to the merchant server 110. When the merchant server 110 receives the online purchase order, a request for generating an OTP is initiated. The merchant server 110 sends the request to a payment server, such as payment server 114. In at least one example embodiment, the request for generating the OTP may be sent via application program interface (API) calls. The merchant server 110 sends the request corresponding to a payment transaction of the purchase order to a payment server, such as payment server 114. In an example embodiment, the request may be sent to the payment server 114 via a payment network (not shown in FIG. 1).

The payment server 114 generates an OTP upon receipt of the request from the merchant server 110. The OTP generated by the payment server 114 is provided to the merchant server 110. The merchant server 110 encrypts the OTP to generate a merchant OTP. The merchant server 110 may store the merchant OTP in the database 118 for using in payment transaction of the online purchase order when the online traffic is reduced. In one example, the merchant OTP may be generated by encrypting the OTP using a standard encryption. The merchant OTP may be generated without performing a hashing encryption so as to prevent replication of the OTP and thereby securing the payment transaction using the merchant OTP.

Furthermore, the generated OTP is provided to the customer 102, which is described with reference to FIGS. 2A and 2B. In one example embodiment, the OTP generated by the payment server 114 may be provided to customer 102 via the merchant server 110, which is described with reference to FIG. 2A. In another example embodiment, the OTP may be provided to the customer 102 directly by the payment server 114, which is described with reference to FIG. 2B. The OTP may be provided to the customer 102 using a mobile number of the customer 102 registered to the merchant site. In an illustrative example scenario, a customer profile of the customer 102 may be maintained by the merchant server 110. The customer profile may be stored in the database 118. The customer profile may include details, such as customer name, shipping address, contact number, email id, or the like. The merchant server 110 may then access the customer profile to retrieve the registered contact number for sending the OTP to the customer 102. In at least one example embodiment, the customer 102 may receive the OTP as a text message. For instance, the OTP may be provided to the customer 102 through a short messaging service (SMS) or an Unstructured Supplementary Service Data (USSD) notification, which is shown in FIG. 5B.

The customer 102 may retrieve the OTP from the SMS or the USSD and provide the OTP in the merchant interface 106. In an illustrative example scenario, the customer 102 may be asked to provide the OTP during an order confirmation in the merchant interface 106, which is shown in FIG. 5B. After receiving the OTP provided by the customer 102 in the merchant interface 106, the OTP is transferred to the merchant server 110. The merchant server 110 locks the online purchase order in the e-cart upon receipt of the OTP provided the customer 102. Further, the OTP provided by the customer 102 is stored in the database 118 by the merchant server 110. The merchant server 110 encrypts the OTP provided by the customer 102 to generate a customer OTP. The customer OTP is sent to an issuer server 116 by the merchant server 110 for the payment transaction of the locked online purchase order. The issuer server 116 is associated with a financial institution normally called as a “issuer bank” or an “issuing bank” or an “issuer bank” or simply an “issuer”, in which the customer 102 may have an account.

The payment transaction for the purchase order may be initiated when an online traffic, such as the customer traffic on the merchant server 110 is reduced, which is described further in FIGS. 3A and 3B. When the customer traffic is reduced, the merchant server 110 may send a payment transaction request along with the merchant OTP to an acquirer sever, such as the acquirer server 112. The acquirer server 112 is associated with a financial institution normally called as a “merchant bank” or an “acquiring bank” or an “acquirer bank” or simply an “acquirer”, in which the merchant site or the service provider entities may have an account.

The merchant server 110 sends the payment transaction request and the merchant OTP to the acquirer server 112 via the network 108 and a payment network. Examples of the payment network include, but not limited to, Mastercard® payment system interchange network. The Mastercard® payment system interchange network is a proprietary communications standard promulgated by Mastercard International Incorporated® for the exchange of financial transaction data between financial institutions that are members of Mastercard International Incorporated®. (Mastercard is a registered trademark of Mastercard International Incorporated located in Purchase, N.Y.).

The acquirer server 112 transfers the payment transaction request and the merchant OTP to the payment server 114. The payment server 114 further transfers the payment transaction request and the merchant OTP to the issuer server 116. After sending the payment transaction request and the merchant OTP, the merchant server 110 may send the customer OTP to the issuer server 116, which is described further with reference to FIGS. 3A and 3B. The issuer server 116 validates both the merchant OTP and the customer OTP by matching both the OTPs. Upon successful validation of the merchant OTP and the customer OTP, a payment authorization for the payment transaction of the locked online purchase order is performed. In one example scenario, the payment authorization may be successful and the payment transaction is completed. In another example scenario, the payment authorization may fail due to issues, such as limited fund in account of the customer 102, temporary issues in payment card of the customer 102, etc. In such scenario, the merchant server 110 may be notified about the payment authorization failure. The merchant server 110 may request the issuer server 116 to provide one or more alternative payment options for completing the payment transaction, which is described with reference to FIGS. 4A and 4B.

Some non-exhaustive example embodiments for providing payment transactions of online purchase orders in online traffic based on provision of locking the online purchase orders and completing the payment transactions for the locked online purchase orders using OTP generated by a payment server, is described with reference to FIGS. 2 to 6A-6B.

FIG. 2A represents a sequence flow diagram 200 of locking an online purchase order of the customer 102 for at least one item at a set price using an OTP generated by the payment server 114, in accordance with an example embodiment of the present disclosure. In an illustrative example scenario, the customer 102 performs an online purchase of an item (e.g., product and/or service) from a merchant site (e.g., the merchant interface 106 in FIG. 1) using an electronic device (e.g., the electronic device 104 in FIG. 1) when there is a significant online traffic at the merchant site, or there is an ongoing discounted sale period at the merchant site.

At 202, the customer 102 makes an online purchase order from the merchant interface 106 using the electronic device 104. At 204, the customer 102 may be directed to a check out page displaying summary of the purchase order.

At 206, the customer 102 provides payment related information, such as information related to payment transaction for the online purchase order during the check out. In an example, the customer 102 may be required to provide payment card information, a payment option, etc. If profile of the customer 102 is not updated with the merchant interface 106, the customer 102 also provides information such as contact details, name, address, and the like.

At 208, the merchant interface 106 submits information of the online purchase order to the merchant server 110. The online purchase order information may include, but not limited to, a summary of the purchase order, a customer name, a shipping address, a contact number and a payment amount for the purchase order.

At 210, the merchant server 110 sends a request to the payment server 114 for generating an OTP corresponding to a payment transaction for the online purchase order. At 212, OTP generated by the payment server 114, upon receipt of the request, is sent to the merchant server 110.

At 214, the OTP generated by the payment server 114 is encrypted by the merchant server 110 to generate a merchant OTP. At 216, the merchant OTP is stored. In an example embodiment, the merchant OTP may be stored in the database 118 shown in FIG. 1.

At 218, the merchant server 110 accesses a registered contact identifier of the customer 102. An example of the registered contact identifier is a registered mobile number (also referred to as “registered contact number”) of the customer 102. Another example of the registered contact identifier is a registered Email identifier (also referred to as “Email ID”) of the customer 102. More specifically, a customer profile of the customer 102 may be stored in the database 118. The merchant server 110 may access the customer profile to obtain the registered contact number of the customer 102. It may also be noted that the merchant server 110 may access a registered email ID of the customer 102 instead of the contact number for sending the OTP.

At 220, the OTP generated by the payment server 114 is sent to the customer 102 by the merchant server 110 using the registered contact ID. In an illustrative example scenario, the merchant server 110 may send the OTP via mobile communication network operator of the register mobile number. The network operator may forward the OTP to the registered contact number of the customer 102.

At 222, the customer 102 is asked to input a customer OTP in the merchant interface 106. The customer 102 is supposed to input the received OTP in the merchant interface 106. At 224, the customer 102 enters the OTP in the merchant interface 106. At 226, the merchant interface 106 submits the OTP provided by the customer 102 to the merchant server 110. At 228, the merchant server 110 receives the OTP and stores the OTP provided by the customer 102 as the customer OTP. The OTP provided by the customer 102 may be stored in the database 118 shown in FIG. 1.

At 230, the online purchase order of the customer 102 is locked for the set price upon receiving the OTP provided by the customer 102. For instance, if the price for the item during the ongoing discounted sale period is $75, the purchase order of the customer 102 (in which total billed value is calculated based on the item cost of $75) is locked, and the item is reserved for the customer 102. It will be appreciated by those skilled in the art that till now the payment account of the customer 102 is not debited, and in fact the merchant server 110 has not even sent the payment transaction request to the payment server 114, and the online purchase order of the customer 102 is locked.

At 232, a notification on locking the online purchase order is sent to the merchant interface 106 by the merchant server 110. At 234, the online purchase order being locked is displayed to the customer 102. It is to be noted that entire payment transaction is not completed by following the operations 202 to 234, and only the item to be purchased by the customer 102 is locked for the price of the item. More specifically, the customer OTP received by the merchant server 110 is not sent to the payment server 114 for any comparison or verification purposes. In various embodiments of present disclosure, the payment transaction is attempted for completion after a pre-defined time period, after expiry of sale period, or when the online traffic at the merchant interface 106 and/or merchant server 110 is less than a threshold online traffic. One example of completion of the online purchase is explained with reference to FIGS. 3A and 3B

In another example embodiment, the OTP may be provided to the customer 102 directly by the payment server 114 instead of the merchant server 110, which is explained next with reference to FIG. 2B.

FIG. 2B represents a sequence flow diagram 240 of locking the online purchase order, in accordance with another example embodiment of the present disclosure.

At 242, the customer 102 makes an online purchase order in the merchant interface 106 using the electronic device 104. At 244, the customer 102 is directed to a check out page displaying summary of the purchase order.

At 246, the customer 102 provides payment related information, such as information related to payment transaction for the online purchase order during the check out. The information may include customer name along with details related to payment information, such as payment options, information of one or more payment cards of the customer 102, etc. At 248, the merchant interface 106 submits the information of the online purchase order to the merchant server 110.

At 250, the merchant server 110 sends a request to the payment server 114 for generating an OTP corresponding to a payment transaction for the online purchase order. At 252, the OTP generated by the payment server 114, upon receipt of the request, is sent to the merchant server 110.

At 254, the merchant server 110 encrypts the OTP to generate a merchant OTP. At 256, the merchant server 110 stores the merchant OTP. For example, the merchant OTP may be stored in the database 118 shown in FIG. 1.

At 258, the merchant server 110 accesses a registered mobile number of the customer 102. More specifically, the merchant server 110 may access a customer profile of the customer 102 to retrieve the registered contact number.

At 260, the registered contact number of the customer 102 is sent to the payment server 114 by the merchant server 110. At 262, the OTP is provided to the customer 102 by the payment server 114 using the registered contact number. For example, the payment server 114 may send the OTP to the customer 102 via a mobile communication network operator associated with the registered contact number. The network operator may forward the OTP to the registered contact number of the customer 102. In an alternate embodiment, the OTP may be provided to a registered email ID of the customer 102. In this embodiment, the payment server 114 may already have the access of the email ID of the customer 102 if the customer 102 is registered with the payment server 114. Alternatively, the payment server 114 can obtain the email ID from the merchant server 110 as the customer 102 is already registered with the merchant server 110.

At 264, the customer 102 is asked to provide the received OTP in the merchant interface 106. At 266, the customer 102 enters the OTP in the merchant interface 106.

At 268, the OTP provided by the customer 102 in the merchant interface 106 is sent to the merchant server 110. At 270, the merchant server 110 stores the OTP provided by the customer 102. At 272, the merchant server 110 locks the online purchase order of the customer 102.

At 274, a notification of locking the online purchase order is provided to the merchant interface 106 by the merchant server 110. At 276, the online purchase order being locked is displayed to the customer 102 on his electronic device 104.

A payment transaction for the locked online purchase order is performed after the expiry of a time period, wherein the time period is determined based on how much time is left for the completion of the ongoing sale period, or an instant when the online traffic is reduced below the threshold level. An example of performing the payment transaction is explained further with reference to FIGS. 3A and 3B.

FIG. 3A represents a sequence flow diagram 300 of a payment transaction for a locked online purchase order of the customer 102, in accordance with an example embodiment of the present disclosure. The payment transaction of the purchase order may be initiated in scenarios such as when the current online traffic is less the threshold level, or after a pre-defined time period, or at the end of discount or sale period. On occurrence of any of these scenarios, the merchant server 110 (shown in FIG. 1) initiates a payment transaction request. The merchant server 110 accesses the merchant OTP stored in a database (e.g., the database 118 described with reference to FIG. 1).

At 302, the merchant server 110 sends the payment transaction request and the merchant OTP to the acquirer server 112. At 304, the merchant server 110 accesses the OTP provided by the customer 102. At 306, the OTP provided by the customer 102 is encrypted to generate a customer OTP by the merchant server 110. In an embodiment, the OTP provided by the customer 102 may be encrypted using a public key. The public key may be provided by the issuer server 116 to encrypt the OTP. For example, the merchant server 110 may communicate with the issuer server 116 using a transport layer security protocol. In an example scenario, an acquirer server 112 of the merchant site and an issuer server 116 of the customer 102 may belong to one financial institution. In such scenario, the merchant server 110 may directly communicate with the issuer server 116.

At 308, the customer OTP is sent to the issuer server 116 by the merchant server 110. At 310, the acquirer server 112 transfers the payment transaction request and the merchant OTP to the payment server 114. At 312, the payment server 114 further transfers the payment transaction request and the merchant OTP to the issuer server 116.

At 314, the issuer server 116 validates the merchant OTP and the customer OTP. More specifically, the merchant OTP and the customer OTP are decrypted by the issuer server 116. If both the OTPs, such as the customer OTP and the merchant OTP, are the same, the issuer server 116 validates the customer OTP.

At 316, the issuer server 116 performs a payment authorization for the payment transaction of the locked online purchase order. The step of payment authorization may include, among other things, checking eligibility of payment account and the available balance in payment account of the customer 102. After successful payment authorization, a payment amount is debited from account of the customer 102.

At 318, the issuer server 116 transfers the payment amount to the payment server 114. At 320, the payment server 114 transfers the payment amount to the acquirer server 112. At 322, the acquirer server 112 sends a payment confirmation to the merchant server 110. At 324, the merchant server 110 forwards the payment confirmation to the merchant interface 106.

At 326, the merchant server 110 sends an acknowledgement to the issuer server 116. At 328, shipment notification for the online purchase order is generated and sent to the customer 102 after receiving the payment confirmation. The shipment notification can also be displayed in the merchant interface 106 when the customer 102 logins into the merchant interface 106.

In another example scenario, the acquirer server 112 of the merchant interface 106 and the issuer server 116 of the customer 102 may belong to different financial institutions. In such scenario, the merchant server 110 may send the customer OTP to the issuer server 116 via the payment server 114, which is described with reference to FIG. 3B.

Referring now to FIG. 3B, a sequence flow diagram 330 of a payment transaction for the locked purchase order of the customer is illustrated in accordance with another example embodiment of the present disclosure.

At 332, the merchant server sends a payment transaction request and a merchant OTP to the acquirer server 112. At 334, the acquirer server 112 transfers the payment transaction request and the merchant OTP to the payment server 114. At 336, the payment server 114 further transfers the payment transaction request and the merchant OTP to the issuer server 116.

At 338, the merchant server 110 retrieves the OTP provided by the customer 102. At 340, the OTP provided by the customer 102 is encrypted by the merchant server 110 to generate a customer OTP.

At 342, the merchant server 110 sends the customer OTP to the acquirer server 112. At 344, the acquirer server 112 transfers the customer OTP to the payment server 114. At 346, the payment server 114 further transfers the customer OTP to the issuer server 116.

At 348, the issuer server 116 validates the merchant OTP and the customer OTP as described in operation 314 with reference to FIG. 3A. At 350, the issuer server 116 performs a payment authorization for the payment transaction of the locked online purchase order as described in operation 316 with reference to FIG. 3A.

At 352, the issuer server 116 transfers the payment amount to the payment server 114. At 354, the payment server 114 transfers the payment amount to the acquirer server 112.

At 356, the acquirer server 112 sends a payment confirmation to the merchant server 110. At 358, the merchant server 110 forwards the payment confirmation to the merchant interface 106. At 360, the merchant server 110 sends an acknowledgement on receiving the payment confirmation to the issuer server 116. At 362, shipment information for the online purchase order is generated and sent to the customer 102.

In one example scenario, the payment authorization for the payment transaction of the online purchase order may fail. In such scenario, the merchant server 110 may request for one or more alternative payment options to the issuer server 116 for completing the payment transaction, which is explained next with reference to FIGS. 4A and 4B.

Referring now to FIG. 4A, a sequence flow diagram 400 of sending a request for providing one or more alternative payment options in case of a payment authorization failure for the online purchase order, is illustrated in accordance with an example embodiment of the present disclosure. In an illustrative example scenario, the acquirer server 112 and the issuer server 116 may be same for a merchant. In such scenario, when there is a payment authorization failure, the merchant server 110 may directly send a request to the customer 102 to provide the one or more alternative payment options.

At 402, the merchant server 110 sends a payment transaction request and the merchant OTP to the acquirer server 112. At 404, the merchant server 110 accesses the OTP provided by the customer 102 in the merchant interface 106. At 406, the merchant server 110 encrypts the OTP to generate a customer OTP. At 408, the merchant server 110 sends the customer OTP to the issuer server 116.

At 410, the acquirer server 112 transfers the payment transaction request and the merchant OTP to the payment server 114. At 412, the payment server 114 further transfers the payment transaction request and the merchant OTP to the issuer server 116.

At 414, the issuer server 116 validates the merchant OTP and the customer OTP to find out if both OTPs are same. At 416, a payment authorization for payment transaction of the locked online purchase order be a failure. For example, the payment authorization may fail due to insufficient balance in account of the customer 102 or due to both OTPs not matching to each other.

At 418, the issuer server 116 sends a message of payment authorization failure to the payment server 114. At 420, the payment server 114 transfers the payment authorization failure to the acquirer server 112. At 422, the acquirer server 112 further transfers the payment authorization failure to the merchant server 110.

At 424, the merchant server 110 sends a notification of the payment authorization failure to the customer 102 and optionally also to merchant interface 106. At 426, the merchant server 110 sends a request to provide one or more alternative payment options to the customer using the registered contact IDs of the customer 102. For example, the merchant server 110 sends a notification to use alternate payment options to complete the payment transaction to the customer 102 through email or SMS to the contact number of the customer 102. Alternatively or additionally, if the customer 102 has downloaded an application associated with the merchant interface 106, a notification to use alternate payment options to complete the payment transaction for the locked purchase order can be sent through the application associated with the merchant interface 106.

In another example scenario, the acquirer server 112 and the issuer server 116 may belong to different financial institutions. In such scenario, when a payment authorization failure occurs, the request for the issuer server 116 to provide one or more alternative payment options may be sent through the payment server 114. The process of sending the request to the issuer server 116 for providing one or more alternative payment options through the payment server 114 is described next with reference to FIG. 4B.

Referring now to FIG. 4B, a sequence flow diagram 440 of sending a request for providing one or more alternative payment options in a payment authorization failure for the online purchase order is illustrated, in accordance with another example embodiment of the present disclosure.

At 442, the merchant server 110 sends the payment transaction request and the merchant OTP to the acquirer server 112. At 444, the acquirer server 112 transfers the payment transaction request and the merchant OTP to the payment server 114. At 446, the payment server 114 further transfers the payment transaction request and the merchant OTP to the issuer server 116.

At 448, the merchant server 110 accesses the OTP provided by the customer 102 in the merchant interface 106. At 450, the merchant server 110 encrypts the OTP to generate a customer OTP. At 452, the merchant server 110 transfers the customer OTP to the acquirer server 112. At 454, the acquirer server 112 provides the customer OTP to the payment server 114. At 456, the payment server 114 further provides the customer OTP to the issuer server 116.

At 458, the issuer server 116 validates the merchant OTP and the customer OTP. At 460, a payment authorization failure for payment transaction of the locked online purchase order occurs due to failure of validations of the merchant OTP and the customer OTP.

At 462, the issuer server 116 notifies a payment authorization failure to the payment server 114. At 464, the payment server 114 notifies the payment authorization failure to the acquirer server 112. At 466, the acquirer server 112 further notifies the payment authorization failure to the merchant server 110. At 468, the merchant server 110 sends a notification on the payment authorization failure to the customer 102 via one or more channels such as SMS sent on registered mobile number of the customer 102, Email on registered email ID of the customer 102 or in an application associated with the merchant interface 106 installed on the electronic device 104 of the customer 102.

At 470, the merchant server 110 sends a request to provide one or more alternative payment options to the customer 102 using available means such as customer mobile number, Email ID or through the merchant application available or installed in the electronic device 104 of the customer 102.

In one example embodiment, the merchant server 110 may provide the merchant interface 106 that causes display of one or more user interfaces (UIs) for receiving inputs from the customer 102 in a check out page, for receiving an OTP in an order confirmation page and for displaying shipping details in an order shipment page. Without loss of generality, some examples of the UIs displayed to the customer 102 are described with reference to FIGS. 5A-5C.

Referring now to FIG. 5A, an example representation of a UI 500 displayed to the customer 102 on a display screen of an electronic device, such as the electronic device 104 displaying a checkout page 510 in the merchant interface 106 is shown in accordance with an example embodiment of the present disclosure. The electronic device 104 and the merchant interface 106 are described in FIG. 1. The UI 500 is an exemplary display of a check out page for a purchase order of the customer 102.

As shown in FIG. 5A, the checkout page 510 is depicted to include a header portion 512 and a content portion 514. The header portion 512 is depicted to exemplarily display a title associated with text ‘CHECKOUT’. As shown in FIG. 5A, the content portion 514 includes an order summary, a customer name, a selection option for different payment methods (e.g., see Credit Card), and a payment card information 516. The content portion 514 is an example representation, and it can be customized in a variety of different ways than that of shown in FIG. 5A.

The customer 102 may provide required information for checking out of the purchase order. The information provided by the customer 102 corresponding to the online purchase order may be submitted by clicking on a submit button, such as submit button 518. After submitting the purchase order, the merchant interface 106 may present one or more UIs for order confirmation of the purchase order.

As explained with reference to FIGS. 2A and 2B, the merchant interface 106 submits the purchase order information to the merchant server 110. The merchant server 110 initiates a request to the payment server 114 for generating an OTP, upon receiving the purchase order information. The OTP generated by the payment server 114 is provided to the merchant server 110. The OTP is further provided to the customer 102, which is shown in FIG. 5B. The customer 102 may be required to provide the OTP in an order confirmation page, which is described next with reference to FIG. 5B.

Referring now to FIG. 5B, an example representation of the UI 500 displayed to the customer 102 on the display screen of the electronic device 104 displaying receiving of an OTP in an order confirmation page 520, such as OTP 528 generated by the payment server 114 and using the OTP 528 for locking the online purchase order in an order confirmation page 550 is shown in accordance with an example embodiment of the present disclosure. The order confirmation page 520 is presented to the customer 102 in response to the submission of the purchase order in the checkout page 510 (shown in FIG. 5A).

As shown in FIG. 5B, the order confirmation page 520 is depicted to include a header portion 522 and a content portion 524. The header portion 522 is depicted to exemplarily display a title associated with text ‘ORDER CONFIRMATION’. The content portion 524 is depicted to include an input field, such as an OTP field 526 for accepting an OTP 528 from the customer 102. As explained with reference to FIGS. 2A and 2B, the customer 102 may receive the OTP 528 through a registered contact number of the customer 102. In an illustrative example scenario, the customer 102 may receive a message with the OTP. As shown in FIG. 5B, the customer 102 may receive message 529 with the OTP 528. The message 529 may include an SMS or a USSD notification. The OTP 528 is entered in the OTP field 526 by the customer 102.

The customer 102 clicks on a send button, such as send button 527 after entering the OTP 528. When the customer 102 clicks on the send button 527, the OTP 528 is sent to the merchant server 110.

As explained with reference to FIGS. 2A and 2B, the merchant server 110 receives the OTP 528 and stores the OTP 528 for completing the payment transaction for the locked purchase order. After receiving the order confirmation, a status of the purchase order being locked is displayed to the customer 102. An example UI provisioned to the customer 102 for displaying the locked purchase order in an order shipment page is shown in FIG. 5C.

Referring now to FIG. 5C, an example representation of the UI 500 displayed to the customer 102 on a display screen of the electronic device 104 displaying shipment information after locking the online purchase order in an order shipment page 530 is shown, in accordance with an example embodiment of the present disclosure. The order shipment page 530 is depicted to include a header portion 532 and a content portion 534. The header portion 532 is depicted to include a title associated with text ‘ORDER SHIPMENT’. The content portion 534 is depicted to include shipment information of the locked online purchase order. The content portion 534 is further depicted to include a text 536 associated with ‘PURCHASE ORDER IS LOCKED’ displayed to the customer 102.

FIG. 6A illustrates a flow diagram 600 depicting a method for providing payment transactions in online traffic, in accordance with an example embodiment of the present disclosure. The method depicted in the flow diagram 600 may be executed by a server system, for example, the merchant server 110. Operations of the flow diagram 600, and combinations of operation in the flow diagram 600, may be implemented by, for example, hardware, firmware, a processor, circuitry and/or a different device associated with the execution of software that includes one or more computer program instructions. The method starts at operation 602.

At operation 602, the method includes receiving an online purchase request in a merchant interface from an electronic device associated with a customer such as the customer 102. The online purchase request includes payment related information of a payment card associated with the customer 102 for purchasing at least one item at a set price. For instance, the customer 102 wants to purchase a book in a discounted sale period offered by online portal of the merchant. The customer 102 accesses the merchant interface 106 through the merchant application or web browser and selects the item (such as a book), quantity and provides the payment related information to the merchant interface 106. It is noted that during the discounted sale period, the book is sold at a set price (e.g., $75), which may be lower than its standard price during no sale periods.

At 604, the method includes sending an OTP request to a payment server (e.g., the payment server 114) associated with a payment network. The server system for instance the merchant server 110 may send the OTP request to the payment server via an acquirer server (e.g., the acquirer server 112).

At 606, the method includes receiving an OTP from the payment server.

At 608, the method includes storing the OTP as a merchant OTP in a database accessible to the server system.

At 610, the method includes facilitating sending the OTP to a registered contact identifier of the customer. Examples of the registered contact identifier may include but not limited to registered contact number such as mobile number, registered Email ID, or any other identifier which can be used to communicate with the customer. The OPT may be sent in form of SMS, or call or Email, Voice message, or multimedia message.

At 612, the method includes providing an option to the customer to input a customer OTP in the merchant interface. For instance, a text box, or voice input means can be provided in the merchant interface for the customer to provide a customer OTP. It is noted that the customer is supposed to provide the OTP received by the customer at the registered contact ID of the customer as the customer OPT in the merchant interface.

Upon receipt of the customer OTP from the customer, at 614, the method includes locking an online purchase order of the at least one item (such as a book) for the set price based on one or more conditions. It is noted that set price, such as $75, is locked for the online purchase order, and online purchase order is accepted, however the payment transaction is not completed. The online purchase order is locked for a time period that is based on one or more conditions, and it can be customized as well. Some examples of the one or more conditions may include network related conditions, item related conditions, and customer related conditions. Example of the network related conditions may include 1. current load of network traffic at the server system, 2. current success/failure rates of other payment transactions performed by the server system, 3. Internet speed, 4. Type of devices used by the customer and the server system and the like. Examples of the item related conditions include 1. How much time is left for the discounted sale period, 2. Availability of the item with the merchant, 3. Cost of the item, and the like. Examples of the customer related conditions include 1. How is the credit history of the customer 2. Has customer been part of similar transaction in which purchase order was locked and the customer made successful payment later, 3. type of payment account of the customer, and the like.

Once the time period for which the online purchase order is locked elapses, the method depicted in flow diagram 600 includes actuating the payment transaction as explained with reference to FIGS. 3A, 3B. For instance, the server system, such as the merchant server, sends the customer OTP to the issuer server of the customer. Also the merchant sever sends the payment transaction request and the merchant OTP to the payment server, which in turn sends it to the issuer sever. The issuer validates the merchant OTP and the customer OTP to perform a payment authorization for the payment transaction of the locked online purchase order, which is described in FIGS. 3A and 3B. For instance, once the issuer server has both the OTPs, such as the customer OTP and the merchant OTP, the issuer server performs validation of the OTPs for example, by matching if both the OTPs are same. Once the validation is successful, payment transaction is approved and processed, and notification is sent to the customer and the merchant. In case the payment transaction is declined, the customer may be notified to provide one or more alternate payment options for completing the payment transaction, which is described in FIGS. 4A and 4B.

FIG. 6B illustrates a flow diagram 620 depicting a method for providing payment transactions when there is increased online traffic, in accordance with another example embodiment of the present disclosure. The method depicted in the flow diagram 620 may be executed by a server system, for example, the merchant server 110. Operations of the flow diagram 620, and combinations of operation in the flow diagram 620, may be implemented by, for example, hardware, firmware, a processor, circuitry and/or a different device associated with the execution of software that includes one or more computer program instructions. The method starts at operation 622.

At operation 622, the method includes receiving an online purchase request in a merchant interface from an electronic device associated with a customer such as the customer 102. The operation 622 is same as the operation 602 described with reference to FIG. 6A.

At operation 624, the method includes determining one of: 1. current online traffic and 2. if there is a sale period associated with the at least one item.

At 626, the method includes sending an OTP request to a payment server (e.g., the payment server 114) associated with a payment network based on predefined conditions. One predefined condition occurs when the current network online traffic is greater than a threshold network traffic. Another predefined condition occurs if there is an ongoing sale period for the at least one item to be purchased by the customer.

At 628, the method includes receiving an OTP from the payment server.

At 630, the method includes storing the OTP as a merchant OTP in a database accessible to the server system.

At 632, the method includes facilitating sending the OTP to a registered contact identifier of the customer. Examples of the registered contact identifier may include but not limited to registered contact number such as mobile number, registered Email ID, or any other identifier which can be used to communicate with the customer. The OPT may be sent in form of SMS, or call or Email, Voice message, or multimedia message.

At 634, the method includes providing an option to the customer to input a customer OTP in the merchant interface. For instance, a text box, or voice input means can be provided in the merchant interface for the customer to provide a customer OTP. It is noted that the customer is supposed to provide the OTP received by the customer at the registered contact ID of the customer as the customer OPT in the merchant interface.

Upon receipt of the customer OTP from the customer, at 636, the method includes locking an online purchase order of the at least one item (such as a book) for the set price based on one or more conditions. It is noted that the set price, such as $75, is locked for the online purchase order. In one embodiment, the online purchase order is locked for a time period that is based on one or more conditions described with reference to FIG. 6A.

Once the time period for which the online purchase order is locked elapses, at 638, the method includes facilitating processing of payment transaction from the payment card for the locked online purchase order. The payment transaction is processed based at least on validating the merchant OTP and the customer OTP provided as input by the customer, as described with reference to FIGS. 3A and 3B.

In one embodiment, the payment transaction is processed after a time period of locking of the online purchase order, wherein the time period is determined based on the one or more conditions. For instance, one condition may be a time instant when the current online traffic becomes less than the threshold level of online traffic. Another condition may be the completion of the ongoing sale period. Another condition may be a fixed time out period defined by the merchant or the customer.

The sequence of operations of the method depicted in flow diagram 620 need not be necessarily executed in the same order as they are presented. Further, one or more operations may be grouped together and performed in form of a single step, or one operation may have several sub-steps that may be performed in parallel or in sequential manner.

FIG. 7 is a simplified block diagram of a server system 700 for facilitating payment transactions for online purchase orders in online traffic, in accordance with an embodiment of the present disclosure. The server system 700 is an example of a server system (e.g., the payment server 114). The server system 700 includes a computer system 702 and a database 704.

The computer system 702 includes at least one processor 706 configured to execute executable instructions for providing various features of the present disclosure. The executing instructions are stored in a memory 708.

The processor 706 is operatively coupled to a communication interface 710 such that computer system 702 is capable of communicating with a remote device 720 such as the electronic device 104, the merchant server 110, or communicates with any entity connected to the network 108 (shown in FIG. 1) or any constituents of the payment network. In an embodiment, the communication interface 710 is configured to receive a request from a merchant server (e.g., the merchant server 110 in FIG. 1) for generation of an OTP corresponding to a payment transaction of a purchase order of the customer 102. Further, the communication interface 710 facilitates provision of the OTP to the merchant server upon receipt of the request. Moreover, the communication interface 710 may receive a payment transaction request along with a merchant OTP and a customer OTP from the remote device 720. The communication may be achieved through API calls, without loss of generality.

The processor 706 may also be operatively coupled to the database 704. The database 704 is any computer-operated hardware suitable for storing and/or retrieving data, such as, but not limited to, information of the customer 102, OTP provided to the merchant server, OTP provided by the customer 102 in the merchant interface 106, transaction data generated as part of sales activities conducted over the bankcard network including data relating to merchants, payees, or customers, and purchases. The database 704 may also store information related to a plurality of bank accounts of customers. Each user account data includes at least one of a cardholder name, a cardholder address, an account number, MPIN, and other account identifier. The database 704 may also include instructions for settling transactions including merchant bank account information.
